Re: [Quickfixj-users] SessionSettings gets cleared out

SourceForge Headquarters 1320 Columbia Street Suite 310 San Diego, CA 92101 +1 (858) 422-6466

Hi,

I heard recently that "old" dynamic sessions were not properly removed before QFJ 2.1.0. So maybe 
this is a side effect of this. But just a wild guess though.
Anyway, please open a JIRA issue for this. Of course it would be the best if we could reproduce it. :)

I briefly tested if this is a general problem but it does not seem likely. E.g. when I comment line 
https://github.com/quickfix-j/quickfixj/blob/fcee00fb1709bc3f1c62b9a893c0e38d873fd312/quickfixj-core/src/test/java/quickfix/mina/acceptor/DynamicAcceptorSessionProviderTest.java#L195 
then the test fails with the error message "Missing ConnectionType". However, when I add

ownSettings.setString("ConnectionType", "acceptor");

, i.e. adding the ConnectionType to the DEFAULT section, the test passes.

Cheers,
Chris.
